The Chevy P0171 code is a trouble code that indicates a lean condition in the engine. This can be caused by a number of different things, but most often it is due to an issue with the fuel system. In order to troubleshoot the problem, it is important to understand what causes a lean condition and how to fix it.
If your Chevy is displaying a P0171 code, it means that the engine is running lean. This can be caused by a number of things, but the most common culprit is a dirty or faulty Mass Air Flow (MAF) sensor.
A MAF sensor measures the amount of air flowing into the engine so that the computer can adjust the fuel mixture accordingly.
If it’s not working properly, too much fuel will be injected and your engine will run lean. Other possible causes of a P0171 code include a vacuum leak, an exhaust leak, or a problem with the oxygen sensor. Whatever the cause, it’s important to get it fixed as soon as possible because running lean can lead to engine damage.
If you’re getting a P0171 code on your Chevy, take it to a mechanic and have them check for these common issues.

Will a P0171 Code Clear Itself
If you have a P0171 code, it means that your engine is running lean. This can be caused by a number of different factors, but the most common cause is a vacuum leak. If you have a vacuum leak, it will allow more air to enter the engine than there is fuel.
This will cause the engine to run lean and trigger the P0171 code. In most cases, a P0171 code will not clear itself. You will need to find and fix the vacuum leak in order to clear the code.
The best way to find a vacuum leak is to use a smoke machine. A smoke machine injects smoke into the engine so you can see where the leaks are coming from. Once you find and fix the leaks, the P0171 code should clear itself.

P0171 Code Chevy Tahoe
If your Chevy Tahoe is displaying a P0171 code, it means that the engine management system has detected a lean condition on Bank 1.
This can be caused by various factors, but the most common culprits are a dirty or faulty Mass Air Flow (MAF) sensor, or a vacuum leak in the intake manifold.
A dirty MAF sensor will cause the engine to run lean because it’s not getting the correct readings of air flow into the engine.
This can be cleaned with some special spray cleaner and a soft cloth. If this doesn’t fix the problem, then you’ll need to replace the MAF sensor.
A vacuum leak will also cause a lean condition because it allows unmetered air into the engine which throws off the fuel mixture.
To check for leaks, use a can of carburetor cleaner and spray around all of the intake hoses and gaskets. If there’s a leak, you’ll hear hissing or see carburetor cleaner being drawn into the hole. These leaks need to be fixed with new gaskets or hoses before moving on.
